I saw an interesting post on gizmodo.com about the consequences of increased use of drones and robots in wars. Anyway, the centerpiece of that post was a documentary by Al Jazeera about that issue. It is somewhat ironic that a news organization called Al Jazeera based in a somewhat benevolent totalitarian regime, does real journalism- unlike the so-called free press in western countries.
In any case, have a look. I am working on two or three longish posts at this moment.
